[xacml] [CR] remove NOTATION from supported types; remove assoc.functions

Text Changes:

  Section 11. Conformance, DataTypes, remove:

    line listing "xs:NOTATION"

  Appendix A.1. Functions, remove:

    function:NOTATION-equal
    function:NOTATION-not-equal

Rationale:

  XML Schema says 
      "It is an error for NOTATION to be used directly
      in a schema.  Only datatypes that are derived from NOTATION by
      specifying a value for enumeration can be used in a schema.

      For compatibility NOTATION should be used only on attributes."

  Also, QName-equal and QName-not-equal can be used to compare
  such data types if necessary.

  I'm on thin ground here, since I don't know enough about XML
  Schema to be sure I am interpreting the impact of this
  correctly.
